.dust may he passed into the hotly of the separator and directed through the upper portion thereof in circular or spiral course, the mejor portion of tie foreign n tte-r hein@ left in the body und passing out through .the tower end thereof.

Another object ot the invention is to pro -vide improved head for the body serving to separute the surplus dust from the air und permittingthe pure nir to out through the open upper end ot the head end causing the dust and a portion ot' the air to he drawn through an outlet arin and return to the fan feeding dust laden air into the separator.

Another object of the invention is to so construct this head that, the halie plates mounted there-in will he iirmly held in place end 'to further so position the outlets for the uit' and surplus dust that the air will have a tendency to incre in a spiral course through the head thus throwing the dust tou'urd the walls of the head und permitting the pure air to pass out through the central outlet formed in the upper n'nll ot the head.

Another object oi the invention is to .so construct this head that it may he removed from the body ot' the separator when so desii-ed".

Another object ot the invention is to pro4 vide a separator which will be very efficient in operation and which wil he comparatively simple in construction.

This invention is illustrated in the acronipanying;l druivings, wherein Figure 1 is a view :showing the improved separator in side elevation. y

This dust separator' is provided with a housing or body 10 having a tapered or conical lower portion 11 terminating at. its lower end in un outlet opening 12 through "which material separated from the air is to pass. The inlet neck or pipe 13 communi- Cates with the upper portion of the body at an angle thereto as shown in Figs. 3 und 6 so that the air driven into the separator from a fan by a suitable conduit Will enter the body and have a tendency to pass about the saine ina circular or spiral course. This niiet-13 communicates with the body at a point/close to the hond Hof the body and in tact the upper wall of this conduit may he a continuation of the head as shown in Fig'. (S. This head 14 is provided with a central openingf from which extends n collar or neclt'fl and in whichl there will be secured the inwardly extending slee vo 16 about which lthe air entering through the inlet 13 will. pass, The pipe or sleeve 17 shown in Fig. 5, i'its `within the Sleeve 1li and from an inspection oi Fig. 2. it will be seen that this pipe 17 extends beneath the lower edge of the sleei'e 18 und to u point, adjacent the upper end of the tapered portion 1l of the body. it will thus be evident that before the air can passup through the pipe or" sleeve 17, it must pass down through the upper portion of the body. ln doinglr so,

the. greater portion of the dust and other foreign matter contained in the air will be 100 forced by the centrifugal force of rotation toward the sides of the 'oodv and will pass down the conical por ion 11 of the body and out through the outlet 12. In the upper portion of this pipe or sleeve 17, vided hridge 18 having a bearing 19 positio. in the center. thereof to receive the a eet screw 21 being provided to ly heid the rod in place.
